Good to know that Zwift has said ‘not officially supported’. I did manage to test it out last night. Zwift (running on iPhone 12 Pro for this test) found the ‘Speed / Cadence’ signal from the Tickr X. And also the HR signal. (screen shots attached)
I don’t have a treadmill, so I headed out for a run. It works - more or less. Yes, Zwift gets the signal, and yes, my avatar moves, but the ‘pace’ in the game is not matching the pace in the real world.
Yes, i was comparing when my avatar was on a flat road.
No, i was not able to calibrate the sensor, since that process requires me to run at 3 different pre-set speeds, and it was hard to judge (outdoors, in the dark, trying to keep an eye out for cars, people, etc )
So i will try to calibrate it in Zwift somehow, and test again.
tl;dr → It works. Not perfect (when using it outdoors). Need to calibrate and test again.
